The rotary drum granulator overcomes many unfavorable factors such as ingredients, particle forming rate, particle strength, output, labor intensity, dust in granulation workshop, cost and so on in the granulation process of disc granulator. It is the preferred granulation equipment for the production of high concentration NPK compound fertilizer. Zhengzhou Huaqiang Heavy Industry Co., Ltd. introduced the drum granulation compound fertilizer production line, and achieved great success in formulation and granulation technology.

Rotary drum granulator is a kind of molding machine which can process raw materials into specific shape. Rotary drum granulator is a link equipment in fertilizer processing industry, which is suitable for cold and hot granulation and mass production of high, medium and low concentration compound fertilizer. Wet granulation is the main method. After a certain amount of water vapor makes the base fertilizer fully react in the cylinder, under a certain liquid condition, with the help of the torsion movement of the cylinder, the extruded pellets are formed between the material particles.

 

The working principle of rotary drum granulator is: the belt and pulley are driven by electricity, the driving shaft is driven by reducer, the split gear installed on the driving shaft is matched with the large gear ring fixed on the body to realize the opposite operation. The material enters the cylinder from the feeding end. Under the special arrangement inside the cylinder, it is made into particles and then flows out through the discharge port. Continuous feeding and continuous twisting granulator can realize batch production.
